SPECIFICATION forming part of" Letters Patent No. 530,300, datedDecember 4, 1894.

Application ned July 9, 1894.

To all whom it may concern:

Be it known that I, ALLEN H. DUNKLE, a citizen of the United States,residing at East Berkley, county of Berks, State of Pennsyl- Vania, haveinvented certain Improvements in Sti1l-Condensers, of which thefollowing is a specification.

This invention relates to improvements in condensing apparatus adaptedmore particu# larly for distilled spirits. p

The invention `is fully described in connec-` tion with the accompanyingdrawing and is specifically set out in the claims.

The drawing is a longitudinal elevation, partly in section of myimproved apparatus.

The condensing chamber A is a vertically arranged pipe closed at bothendsbut provided with an upper inlet a for the spirituous vapors and alower outlet pipe E for the condensed liquid. Arranged Within thischamber is a coiled water pipe B having an inlet b at the bottom and anoutlet b. above the closed top of the chamber.

C is a cooling box which incloses a coiled refrigerator pipe c havingits lower end protruding through the Wall of the chamber and connectedto any convenient water supply, While the upper portion supports aperforated pan or receptacle D which is also inclosed in said coolingbox and forms the terminus` of the outlet pipe E from the condensingchamber. This pipe E is provided with an upward bend c which serves toretain a proper level of condensed liquid in the chamber A, and alsowith a vent pipe e for the escape of any steam or gas which wouldotherwise tend to interfere with the proper dow of the liquid. The upperportion of the refrigerator pipe is extended through the Wall of the boxC and upward through the center of the chamber A, terminating outside ofthe closed top of the latter.

The operation of my improved device is very simple. The pipe ot leadsthe vapor from the distilliug apparatus which may be of any desiredform, into the condensing Serial No. 516,933. (No model.)

chamber A. I-Iere it comes in contact with the large amount ofcondensing surface provided by the exterior of the coiled Water pipe Band the central pipe c', and the interior surface of the y chamber Awhich is itself cooled by the overow water from the protruding upperends of the pipes B andc. As the vapor descends it is cooled andcondensed and when it reaches the bottom of the vessel it is conveyedthrough the pipe e to the perforated pan D from which it drips throughthe perforations and falls upon the upper fold of the refrigerator` pipec and thence downward over thelower folds to the bottom of the box Cwhere the cooled liquid linde an outlet through a pipe c2. s

Owing to the novel arrangement of my apparatus I am enabled to do alarge amount of Work While occupying a comparatively small amount ofroom and using a minimum amount of Water to effect the purpose.

1. The condensing chamber A provided Vwith inlet and outlet openings, incombination with a central Water pipe c and a coiled water pipe B theends of said water pipes proj ecting through the closed top of thecondensing chamber and discharging thereon so as to overflow theexterior of the chamber, substantially as and for the purpose set forth.

2. A condensing apparatus comprising a condensing chamberA with topinlet thereto,

and a horizontal outlet pipe E from the lower end thereof, said pipebeing provided with an upward bend e, a vent pipe e and a perforatedreceptacle D, in combination with a' box Gand cooling pipes in said boxand in said condensing chamberall arranged and adapted to operatesubstantially as set forth.

x In testimony whereof I aflix my signature in presence oftwowitnesses.` p
